RESERVE NOTICE MT PASA PUBLICATION 24 September 2024
The MTPASA result published on 24 September 2024 identifies Low Reserve Conditions as annual unserved energy exceeds the Reliability Standard between:
-- September 2024 - September 2025 in South Australia.
AEMO declares low reserve conditions in accordance with clause 4.8.4 of the National Electricity Rules for the following region(s) and periods:
-- January 2025 - March 2025 in South Australia when forecast demand exceeds supply under some circumstances.
Please note that MTPASA informs the market of potential reliability issues to allow the market to respond in the first instance, potentially avoiding the need for any AEMO intervention.
For further information, please refer to:
https://www.aemo.com.au/Electricity/National-Electricity-Market-NEM/Data/Market-Management-System-MMS/Projected-Assessment-of-System-Adequacy
This notice supersedes Market Notice 118296 published on 17 September 2024.
Background
As part of a broader process of implementing the reliability standard, AEMO runs the Medium Term Projected Assessment of System Adequacy (MTPASA) process weekly to forecast expected unserved energy levels over a two year period. If the expected annual unserved energy exceeds the maximum level specified by the Reliability Standard, a Low Reserve Condition is identified.
For more information about how AEMO implements the reliability standard, please view the Reliability Standard Implementation Guidelines (RSIG) available on AEMO's website at https://www.aemo.com.au/Electricity/National
